FCC Covered List Is Changing: Why PCS Compliance Matters for Energy Storage

Energy storage systems are becoming more integrated, with components such as power conversion systems (PCS), power inverters, energy management platforms, and communication technologies playing increasingly important roles.

While companies often focus on battery certifications and transportation requirements, PCS and power inverter requirements are becoming increasingly important considerations for U.S. market access. On July 28, 2026, the FCC added foreign-produced power inverters to the Covered List, creating new regulatory considerations for companies supplying energy storage products to the U.S. market.

01. PCS AND POWER INVERTERS ARE BECOMING KEY MARKET ACCESS CONSIDERATIONS

Power conversion systems (PCS) play an essential role in energy storage systems by managing power conversion, grid interaction, and energy management functions.

For companies supplying energy products to the U.S. market, understanding PCS-related information is becoming increasingly important.

Traditionally, companies focused primarily on battery-related requirements when preparing energy storage products for international markets. However, as energy systems become more integrated, other system components are also becoming important considerations for U.S. market preparation.

02. FCC COVERED LIST CHANGES CREATE NEW POWER INVERTER AND PCS MARKET ACCESS REQUIREMENTS

The impact of this regulatory change depends on product models, authorization status, and applicable FCC requirements.

For newly produced power inverter models covered by applicable FCC requirements, companies may face challenges obtaining FCC equipment authorization. This could affect their ability to import, market, or sell these products in the United States.

However, the impact is not the same for all products. Previously authorized models are not automatically affected by the change, and certain products may continue through applicable FCC authorization pathways, including Conditional Approval mechanisms where applicable.

As a result, companies need to review their PCS portfolio, including:

• FCC authorization status
• Product model information
• Supplier and manufacturing details

Rather than assuming previous approvals will apply to future products, companies need better visibility into PCS changes and evolving regulatory requirements.

03. PCS SUPPLY CHAIN VISIBILITY IS BECOMING MORE IMPORTANT

As PCS and power inverters become more relevant to U.S. market access, companies need better visibility into product details and supply chain information.

Changes in PCS models, suppliers, or manufacturing arrangements may create additional considerations when preparing products for the U.S. market.

Companies need to maintain accurate records of:

• PCS model information and specifications
• Supplier and manufacturing details
• Certification and authorization status

Without reliable product information, companies may face difficulties evaluating market access risks and preparing products for U.S. deployment.

For energy storage companies, managing PCS information is becoming an important part of supply chain planning and operational readiness.

04. PCS COMPLIANCE PREPARATION NEEDS TO START EARLY

As regulatory requirements continue to evolve, companies need to prepare product information and supply chain processes before entering the U.S. market.

Early preparation helps companies better manage:

• Product information and documentation
• Inventory planning
• Supplier coordination
• U.S. operational requirements

Companies that connect compliance considerations with supply chain execution will be better positioned to respond to market changes and support long-term U.S. growth.
